There are also 8051 µControllers available that don't need a crystal can do all that is listed and more and are cheaper,...

They don't provide the USB interface.

Have to anyways. Was going to port RepRapFirmware to this.Quote

But they don't come with Arduinoo IDE, so you have to do real programming,.. ;-)
Looking at replacing the FTDI serial converter with a second MCU that can act like a USB-UART chip as well as the ADC and PWM. The USB serial interface on the the second MCU would just take all data on the USB serial interface and spit it out the UART over to the ESP32. The ESP32 would give the second MCU commands over SPI though.Quote

PS: Wasn't the Idea to connect them to the ESP as an SPI slave? So why do they need to have USB?

... I didnt know that could be done. lol.Quote

Or you could send the USB data over SPI instead of UART.

This chip looks like it will work EFM8UB2 and it is only 2 bucks.

I think that reliable USB-Serial conversion could be done on an 8-bit.
